Mizuno ST-X Driver

Mizuno ST-X Driver

Ultra-stable with high draw bias

A draw-biased carbon composite construction aided by a heel side sole weight. Built upon the 2nd generation of Mizuno's Forged SAT2041 Beta Ti face – for potent ball speeds and consistent performance over time. Slower swing speeds will benefit from the J-Spec – incorporating an incredibly lightweight 39g MFusion graphite shaft.


20% Vanadium / 4% Aluminium / 1% Sn

Highly resilient Forged SAT2041 Beta Ti Face

As a high strength Beta Ti, SAT2041 maintains its characteristics and resists micro fractures for longer than the commonly used 6-4 Ti.

New Multi-thickness CORTECH Face structure

Refined to maximize the return from Mizuno's Beta Ti face. Ball speeds most noticeably improved low on the clubface.

'Dense' or solid feedback

The majority of Mizuno's tour players expressed a preference for more dense feedback through impact. Mizuno's engineers spent a year finessing the sound to a more muted, powerful tone.

X-Axis design for draw bias

Expanded toe located carbon composite window, with heel located sole weight combine to produce a reliable draw bias.

Optimized Wave Sole Plate

Delivers an additional contribution to ball speed – especially low from the clubface.

More compact profile

Slightly deeper back portion and more upright visual lie angle.


4 degrees of loft adjustability to fine-tune look and trajectory.
